Yes you just need to use a Format event handler on the Binding object
For example
private void AddBinding() {
Binding b = color1.DataBindings.Add("BackColor", NavBill.DataSource, "Color1", true);
b.Format += PanelBackColorBinding_Format;
}
private void PanelBackColorBinding_Format(Object sender, ConvertEventArgs e) {
if (e.DesiredType == typeof(Color)) {
Int32 number = (Int32)e.Value;
Color col = GetColor(number);
e.Value = col;
}
}
Make sure that a default color is assigned to e.Value if there is any chance that the column will have missing or non convertable values.

Hey Everyone:
I've never done something like this before - announcing the relase of my first NuGet package. (I've had a couple of others but they were really niche.) This is an extension to the MarkDig markdown parser in .NET 6, and I used a tutorial article from here to make it happen! Thanks @cyotek for the big help!
The source code - along with my hopefully coherent documentation - is available at:
GitHub - crazycga/Evergrowth.AspForMarkDigExtension: This is the source repository for the Asp-For MarkDig Extension.[^]
The NuGet package is called "Evergrowth.AspForMarkDigExtension".
What it does:
I had a situation where a client of mine wanted to use markdown to prepare some forms for clients. Semi-static stuff. I found that when I was parsing the markdown in the controller, it wasn't getting parsed properly to make use of the 'asp-for="<model name="">"' function to build input fields. I tilted at that windmill for a time, then decided it would be a good way to grow a little as a developer and get input on my stuff... So here we are.
Thanks everyone here who - over the years - has helped me immeasurably become better at this!
-J

Don't post this here - forums can move pretty rapidly, and once this scrolls off the first page it gets less likely that anyone will ever see it. Plus, it's kinda rude for a "technical forum" to be plugging your work, even a free to use nuget package.
Instead, have you considered posting the Github as a Project here? Provided your documentation is indeed coherent it should be pretty easy to do: Your GitHub Project on CodeProject[^] and that is more likely to be found.

Sorry didn't mean to be rude. Was trying to thank someone for their help and inspiration. And didn't want to have a huge long lasting thing so figured posting in a forum would be good, so that it was ephemeral. For some reason I can't seem to delete to post. If you can, please do so.

If you want to thank someone, reply to a comment they made, or post at the bottom of the article. That way they should notice it* 
Why would you want your work to be ephemeral, if you are sharing it anyway? 
You can't delete your post because it has a reply - that would "orphan" the response(s) and lose the meaning of the thread (obvious if you think about it). Yes I can delete the whole thread (all Protectors can) but it's not necessary it's only "slightly rude" not "you b*****d" rude! I wouldn't worry about it, but if you still want that, just say the word.
* Some people run with emails disabled, or deliberately use a dummy email so "@" messages may not get through at all.

I want to parse multiple html table using htmlagility pack. i want to iterate in all TD and extract values.
please have a look at this url https:
the above url has many tabular data whose html tables i have to parse.
here i am pasting a small snippet of html table. please check how data is stored in this table.
<pre><table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:99.853%"> <tbody> <tr> <td style="width:1.0%"></td> <td style="width:71.960%"></td> <td style="width:0.1%"></td> <td style="width:0.1%"></td> <td style="width:0.532%"></td> <td style="width:0.1%"></td> <td style="width:1.0%"></td> <td style="width:11.637%"></td> <td style="width:0.1%"></td> <td style="width:0.1%"></td> <td style="width:0.532%"></td> <td style="width:0.1%"></td> <td style="width:1.0%"></td> <td style="width:11.639%"></td> <td style="width:0.1%"></td> </tr> <tr style="height:12pt"> <td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:1pt;font-weight:700;line-height:100%"> </span></td> <td colspan="3" style="padding:0 1pt"></td> <td colspan="3" rowspan="2" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:700;line-height:100%">June 30,<br>2023</span></td> <td colspan="3" style="padding:0 1pt"></td> <td colspan="3" rowspan="2" style="padding:2px 1pt;text-align:center;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:700;line-height:100%">December 31,<br>2022</span></td> </tr> <tr style="height:12pt"> <td colspan="3" style="padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:8pt;font-weight:700;line-height:100%">(In thousands, except share data)</span></td> <td colspan="3" style="padding:0 1pt"></td> <td colspan="3" style="padding:0 1pt"></td> </tr> <tr> <td colspan="3" style="background-color:#cceeff;border-top:1pt solid #000000;padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:100%">Assets</span></td> <td colspan="3" style="background-color:#cceeff;padding:0 1pt"></td> <td colspan="3" style="background-color:#cceeff;border-top:1pt solid #000000;padding:2px 1pt;text-align:right;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:1pt;font-weight:700;line-height:100%"> </span></td> <td colspan="3" style="background-color:#cceeff;padding:0 1pt"></td> <td colspan="3" style="background-color:#cceeff;border-top:1pt solid #000000;padding:2px 1pt;text-align:right;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:1pt;font-weight:400;line-height:100%"> </span></td> </tr> <tr> <td colspan="3" style="background-color:#ffffff;padding:2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">Cash and due from banks</span></td> <td colspan="3" style="background-color:#ffffff;padding:0 1pt"></td> <td style="background-color:#ffffff;padding:2px 0 2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">$</span></td> <td style="background-color:#ffffff;padding:2px 0;text-align:right;vertical-align:bottom"> <span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%"> <ix:nonfraction unitref="usd" contextref="c-3" decimals="-3" name="us-gaap:CashAndDueFromBanks" format="ixt:num-dot-decimal" scale="3" id="f-32">120,285</ix:nonfraction> </span> </td> <td style="background-color:#ffffff;padding:2px 1pt 2px 0;text-align:right;vertical-align:bottom"></td> <td colspan="3" style="background-color:#ffffff;padding:0 1pt"></td> <td style="background-color:#ffffff;padding:2px 0 2px 1pt;text-align:left;vertical-align:bottom"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%">$</span></td> <td style="background-color:#ffffff;padding:2px 0;text-align:right;vertical-align:bottom"> <span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:100%"> <ix:nonfraction unitref="usd" contextref="c-4" decimals="-3" name="us-gaap:CashAndDueFromBanks" format="ixt:num-dot-decimal" scale="3" id="f-33">145,342</ix:nonfraction> </span> </td> <td style="background-color:#ffffff;padding:2px 1pt 2px 0;text-align:right;vertical-align:bottom"></td> </tr> </tbody> </table>
Some time TD has direct data and some time TD has SPAN which has data. some time SPAN has custom tag which has data <ix:nonfraction
for a long time i am trying to loop through all TD's of all table and extract data only but getting no success.
here is my code which is trying to iterate and get data but code is not working.
<pre>var table1 = htmlDoc.DocumentNode.SelectNodes("//table");
var tbody = table1.ChildNodes["tbody"];
var lst = new List<Table1>();
foreach (var row in tbody.ChildNodes.Where(r => r.Name == "tr"))
{
var tbl1 = new Table1();
var columnsArray = row.ChildNodes.Where(c => c.Name == "td").ToArray();
for (int i = 0; i < columnsArray.Length; i++)
{
if (i == 0)
tbl1.Course = columnsArray[i].InnerText.Trim();
if (i == 1)
tbl1.Count = columnsArray[i].InnerText.Trim();
if (i == 2)
tbl1.Correct = columnsArray[i].InnerText.Trim();
}
lst.Add(tbl1);
}
Please some one guide me with a sample code which can extract data from html table TR,TD
please please need your support and help to extract data from html tables. thanks

Unfortunately that does not provide us with any useful information as to what happens when you run your code. Please edit your question, and add complete details of what is not working.

The name looked familiar, so I searched messages for it.
If it's the same person, and his question here fits the pattern in the days before, he's an old Assistive Nosferatu we terminated six years ago.
Just a heads up.

Thanks Dave. Let's see how this pans out.

It's a private conversation.
|
|
|
|

if private conversation then why you guys post text in my thread?
why do not create a new thread and gossip there?
|

Because you have a history here. One that got you booted before.

I wondered about that. I thought I'd seen the name. I was sure that Buffy had done her thing with Mr Pointy.

Explain how it is not working.
Also explain what you did to determine exactly where it is failing.

I am thinking you're going to need a lot more information than that.

You're going to have to provide a LOT more information than that. There's only about a thousand things that can be wrong.
We know nothing about your code, how you're retrieving data, any locking involved, normalization, queries you're using, the database, its structure, indexing, ...
Absolutely nothing.
|
|
|
|
|
You would need to figure out exactly which part is slow.
Presuming that it actually a database call then you would need to look at the SQL statements that are being executed.
And the environment. So if you are running 100,000 clients it is going to be far different than if you are running 1.

Hi everyone,
I am new to this community and C# in general, (a PHP guy) but I am hoping I can get some help here. I am trying to have a page display 20 products then, a next button for the other 20 and so on. Below is the code of what I am trying to achieve. (link to image image_new_button.png - Google Drive[^] )
Thanks for your help in advance.
Best regards
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="winners.aspx.cs" Inherits="FrontPanel.winners" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<div class="container">
<h4 class="paddingtb-15">Winner List </h4>
<table class="table table-striped table-bordered"><tr>
<th>Product Details</th>
<th>Amount</th>
<th>User Details</th>
</tr>
<asp:ListView ID="ListView1" runat="server">
<ItemTemplate>
<tr>
<td style="width:600px">
<asp:Image ID="Image1" runat="server" ImageUrl='<%#Eval("productimage") %>' Width="30px" />
<%#Eval("productname") %>
</td>
<td><%#Eval("winamount") %></td>

</tr>
</ItemTemplate>
</asp:ListView>
</table> </div>
</asp:Content>

I don't see you retrieving any. Usually, the question would be: How do I retrieve the "next" 20? Then, the "previous" 20. And so forth.
